BOLSTER.

SPECIFICATION forming part Of Letters Patent No. 721,131, dated February17, 1903. Application filed December 18, 1902. Serial No. 135,802. (Nomodel.)

To a/ZZ whom it may concern:

Be it known that I,JOHN C. WANDS, a citizen of the United States,residing at St. Louis, Missouri, have invented aV certain new and usefulImprovement in Bolsters, of which the.

following is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, forming part ofthis specification, inv which- Figure l is a side elevational view,partly broken away at one end. Fig. 2 is a top plan View of one end ofmy improved bolster. Fig. 3 is a Vertical sectional view ofl the severalparts comprising one end of my improved bolster separated for thepurpose of better showing the details of construction thereof. Fig. 4 isan isometric view of the upper section of the head-block.v Fig. 5 is aninverted plan view of the same. Fig. 6 is a plan view of the lowersection of the head-block. Fig. 7 is an end View of the same, and Fig. 8is a plan view of one end of the tension member of my improved bolster.

This invention relates to anew and useful improvement in bolstersdesigned for use either as truck-holsters or body-holsters.

The object of the invention is to construct a bolster withcommercially-rolled compression and tension members united at their endsby means of head-blocks composed of a plurality of sections adapted tointerlock with each other and with the tension member of said bolster;and the invention consists in certain features of noveltyin theconstruction of the same, all as will be hereinafter more fullydescribed, and specifically pointed out in the claims.

Referring to the drawings, l is the compression member of my improvedbolster, consisting of a com mercially-rolled channel cambered at itscentral portion.

2 is the tension member of my bolster, comprising a flat plate ofcommercially-rolledV metal which has at its end portions a series ofopenings 3, preferably angular in shape.

A is the upper section of the head-block, which section is provided onits upper side with the recess 4, having the downwardlyprojectingrecesses 4.,'the recess t being adapted to receive therein the web ofthe compression member, while the recesses 4a are adapted to receive theflanges of said compression member. The memberA is provided with ashoulder 4b for the end of the compression member, which shoulder servesas a stop therefor. The under side of the section A is recessed, as at5, whereby there is formed a seat for the end of the tension member 2,the lugs or projections 6 extending downwardly from the section A andpassing through said angular openings 3 of the tension member and intoand through the openings 7, formed in the upper face of the lowerhead-block section B, while dowels 8 project upwardly from said sectionB and interlock with recesses 9 in the lower face of the section A,thereby uniting the said sections A and B and, by means of the said lugs6, securing the tension member of the bolster lirmly in position withinthe head-block, the end ofv said compression member abutting against theshoulder 4b of thesection A.

E indicates the king-post or strut, which is preferably formed hollowfor the passage of the king-bolt, said strut being provided with lateralflanges adapted to afford an extended bearing for the compression memberand also provided with webs ll between said flanges and the verticalportion of said king-post, which webs serve to strengthen the same.

The lower section B of the head-block is preferably cast hollow, as bestshown at Figs. 3 and 7, and between the horizontal walls thereof areprovided vertical partitions 12, which serve to strengthen said sectionB, said walls extending from the outer ends thereof to the opposite endof saidsection B.

The sections A and B of thehead-block are both provided withsho'uldersor vertical ribs 13, which serve as column-guides.

In assembling the dierent parts of my improved bolster the tensionmember'is placed in position upon the lower section B, with the openings3 regist'eringwith the openings 7 of said section, whereupontheupper-section A is placed in position with the lugs 6 projectingthrough both series of openings 3- and 7 and passing into the hollowportionrof said section B, after which the strut is placed -in positionon said tension member and the com- IOO pression member is placed uponthe strut. The compression member is not secured permanently to thehead-block nor are the several parts of the head-block permanentlyconnected together, as it will be found that the weight of the car uponthe compression member will be suicient in practice to hold the severalparts in their proper cooperative positions; but, if desirable, atemporary securing means may be used to hold the compression member inplace upon said head-block, which securing means may be any convenientmeans which will accomplish the result, such as a pin passing throughthe ianges of said compression member into the section A of saidhead-block, or any other convenient means may be used, such as the upsetlug 15, integral with the head-block A.

It will be observed that when the parts are assembled for use thesections of the headblock are united by the same means which hold thetension member in position, and it is immaterial whether the lugs 6 becast integral with the upper section A and the openings 7 be formed inthe upper face of the section B or whether said lugs shall projectupwardly from the section B and register with` corresponding recesses inthe section A, as either construction will be Within the spirit of myinvention.

For the purpose of securing the requisite strength the tension member ismade relatively longer than the compression member and, as seen in thedrawings, projects therebeyond for ashort distance at each end Withinthe head-blocks.

The head-block sections and lugs 5 are preferably made of malleablecastings, and to permit the same to be properly annealed are preferablyformed three-eighths of an inch in thickness at all points whereannealing is desirable.

I am aware that minor changes in the construction, arrangement, andcombination of the several parts of my device can be made andsubstituted for those herein shown and described without in the leastdeparting from the nature and principle of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
